# src/Private/StyleProfile/Merge-ShowTreeHashtable.ps1 <# .SYNOPSIS Deep merges two hashtables. .DESCRIPTION The Merge-ShowTreeHashtable cmdlet performs a deep merge of two hashtables. Values from the Override hashtable replace or extend values in the Base hashtable. If a key exists in both and both values are hashtables, they are merged recursively. This is primarily used for applying custom overrides to base style profiles. .PARAMETER Base The base hashtable providing default values. .PARAMETER Override The hashtable containing values that should override or extend the base. #> function Merge-ShowTreeHashtable { [CmdletBinding()] param( [Parameter(Mandatory)] [System.Collections.IDictionary] $Base, [Parameter(Mandatory)] [System.Collections.IDictionary] $Override ) if (-not $PSBoundParameters.ContainsKey('Debug') -and $PSCmdlet) { $DebugPreference = $PSCmdlet.GetVariableValue('DebugPreference') } if (-not $PSBoundParameters.ContainsKey('Verbose') -and $PSCmdlet) { $VerbosePreference = $PSCmdlet.GetVariableValue('VerbosePreference') } $result = @{} foreach ($key in $Base.Keys) { $value = $Base[$key] if ($value -is [System.Collections.IDictionary]) { $child = @{} foreach ($childKey in $value.Keys) { $child[$childKey] = $value[$childKey] } $result[$key] = $child } else { $result[$key] = $value } } foreach ($key in $Override.Keys) { if ( $result.Contains($key) -and $result[$key] -is [System.Collections.IDictionary] -and $Override[$key] -is [System.Collections.IDictionary] ) { $result[$key] = Merge-ShowTreeHashtable -Base $result[$key] -Override $Override[$key] } else { $result[$key] = $Override[$key] } } return $result } |
